An oil system for an engine includes an lubricating oil circulation system having a pan reservoir connected to an inlet of an engine oil gallery by a circulation conduit. A circulation pump is positioned in the circulation conduit. A recirculation conduit connects an outlet from the engine oil gallery to the pan reservoir to complete the lubricating oil circuit. A hydraulically actuated subsystem has a supply conduit connecting the engine lubricating oil circulation system to at least one hydraulically actuated device, such as a hydraulically actuated fuel injector. A high pressure pump is positioned in the supply conduit. A drain conduit connects the at least one hydraulically actuated device to the pan reservoir. A first external port and valve are attached to and open into the supply conduit of the subsystem. An auxiliary pump is connected to the external port. The auxiliary pump can be used to either remove waste oil from the subsystem or to add fresh oil to prime the subsystem in preparation for starting the engine after an oil change.

A method of priming a hydraulically actuated subsystem that is connected to an engine\s lubricating oil circulation system, comprising the steps of: including a first external port that opens to said hydraulically actuated subsystem; including a first port valve in said first external port; opening said first port valve; pumping lubricating oil into said hydraulically actuated subsystem through said first external port until said hydraulically actuated subsystem is at least partially full of lubricating oil; and closing said first port valve.
